Subject: [PATCH] Upload company import packages as compressed zip uploads (fix
large-company imports through Cloud) (#10531)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Company Import (#10507, hardened in #10523) lets a user upload a
company package on the Import page
> - The page expanded the user's `.zip` into a files map and POSTed it
as ONE inline JSON body — ~40MB for a real company because attachment
blobs get base64-inflated
> - On Paperclip Cloud that body travels browser → harness proxy →
tenant, where it truncated in transit → body-parser 400 → the browser
saw "Failed to fetch", and nothing imported
> - Two compounding causes: the giant inline body itself, and the board
async opt-in riding an `x-paperclip-cloud-*` header that the Cloud
harness strips as anti-spoofing (so async never engaged and the import
held one fragile synchronous connection)
> - This pull request uploads the raw compressed `.zip` as a multipart
request (about a third the size, already compressed) parsed server-side
into the same bundle the importer consumes, and moves the async opt-in
to a proxy-safe `?async=1`
> - The benefit is that a large-company import actually completes
through Cloud: a small compressed upload, a real async job that survives
dropped connections
## Linked Issues or Issue Description
- Refs #10507 / #10523 (Import/Export and its hardening). No open issue;
problem described above (large-company browser import through a proxy:
inline JSON body truncates → 400 → "Failed to fetch"; async opt-in
header stripped by the front door → async never engages).
## What Changed
- **Multipart zip transport.** The Import page uploads the raw `File` as
`multipart/form-data` (field `package`, import options in a JSON `meta`
field); the server unzips it into `{ rootPath, files }` and runs the
exact existing preview/import logic. The `application/json` inline path
is byte-identical for CLI/programmatic callers. Bare `application/zip`
(meta via `?meta=`) is also accepted for programmatic use.
- **Shared node zip reader.** `packages/shared/src/portability-zip.ts`
(node-only subpath, not re-exported to the browser bundle — same pattern
as `portability-hash.ts`); the CLI's `zip.ts` becomes a thin re-export.
Identical codec (STORE + DEFLATE via `inflateRawSync`, rejects data
descriptors/zip64).
- **Proxy-safe async signal.** `wantsAsyncImport` = `?async=1` (board
browsers, survives the harness) OR the existing
`x-paperclip-cloud-async-import` header (cloud tenants, set
server-side). The UI async client now uses `?async=1`. Backward
compatible.
- **Size + preflight.** New `PORTABLE_ZIP_UPLOAD_LIMIT_BYTES = 128MB`;
the inline 56MB preflight no longer gates the zip path (it shows the
compressed size instead). Async submit/poll/resume, the duplicate-guard
fingerprint (now over the resolved bundle), pause-on-import,
progress/error panels, and activation all apply to the multipart path.
- OpenAPI documents json + multipart + zip bodies and the `async` query
param.
## Verification
- Full typecheck chain (shared, server, ui, cli) clean.
- 152 tests across 8 files: new `portability-zip.test.ts`
(STORE/DEFLATE/base64-blob byte-exact round-trip, truncation throws,
data-descriptor rejection); `company-portability-routes.test.ts` +7
(multipart import+preview equals the inline bundle; async multipart
202→poll→success; board async via `?async=1` with no cloud header;
cloud-tenant async via header; sync fallback with neither; truncated-zip
400, nothing imported); `CompanyImport.test.tsx` asserts the local zip
sends the raw File and the inline preflight no longer blocks;
`openapi-routes.test.ts` green.
- NOT yet measured: the end-to-end browser upload through the live Cloud
harness — verified on staging after deploy before closing out.
## Risks
- Import semantics unchanged — only transport changed; the JSON inline
path is byte-identical, the cloud-tenant header async path untouched.
Multipart parsing is server-side (memory-bound: a ~13MB zip → ~30MB
files map, fine on the server).
- The bare `application/zip` path is programmatic-only and covered by
content-type dispatch but not a dedicated route test (the multipart path
is).
## Model Used
- Claude Fable 5 (`claude-fable-5`, Anthropic), Claude Code CLI,
extended thinking + tool use; root-caused against live logs/DB and the
harness proxy source.
